Kelly having sex with an underaged girl. A source told TMZ a number of women claiming to be victims of R. Kelly have been shown the tape to see if they can corroborate the location and surroundings. R. Kelly’s attorney called the report false and says he has no knowledge of grand jury proceedings. Attorney Michael Avenatti, who represents whistle-blowers and alleged victims in the case as well as adult film star Stormy Daniels, told WGN he’s provided the video, and a list of witnesses, to Cook County State’s Attorney Kim Foxx. “The tape is within the statute of limitations necessary to charge R. Kelly, and I am confident that in the coming days R. Kelly will be indicted, he will be arrested, and I will be very surprised if he ever walks free another day in his life,” Avenatti told WGN. Avenatti also alleged that R. Kelly used witness intimidation, tampering and bribery to win his acquittal on sexual assault charges in 2008. The Lifetime docu-series “Surviving R. Kelly,” that aired in January, examined R. Kelly’s lifestyle and his alleged penchant for and predatory behavior toward young girls. The documentary sparked a #MuteRKelly movement through social media. Soon after the series aired, Cook County States’s Attorney Kim Foxx held a press conference asking alleged victims to come forward. R. Kelly has also faced the scrutiny of Chicago building inspectors who investigated complaints that he and his associates have been using a Near West Side recording studio for residential living purposes.
